The BPI-M2+ is an H3 development board. It is a smaller form factor than
the original BPI-M2, with the new H3 SoC.

It has 1GB DRAM, 8GB eMMC, a micro SD card slot, HDMI output, 2 USB
host connector and 1 USB OTG connector, an IR receiver, WiFi+BT based
on Ampak AP6212.

The board also has a 3 pin header for (debug) UART, a 40 pin GPIO header
based on the Raspberry Pi B+, but the peripheral signals are not the
same, and an FPC connector for connecting BPI's camera.

The AXP809 PMIC is used with the Allwinner A80 SoC, along with

This patch adds a dtsi file for all the common bindings and default

The memory range assigned to the PMC (Power Management Controller) was
not including the PMC_PCR register which are used to control peripheral
clocks.

This was working fine thanks to the page granularity of ioremap(), but
started to fail when we switched to syscon/regmap, because regmap is
making sure that all accesses are falling into the reserved range.

An error in documentation of the NAND Flash Controller (NFC) led to choose
another compatibility string for sama5d2 with an impact on the NAND flash
ready/busy information. It was producing the error message:

atmel_nand 80000000.nand: Time out to wait for interrupt: 0x08000000

and had an impact on performance.

So, switch back to the classical "atmel,sama5d3-nfc" compatibility string for
this SoC which gives the proper ready/busy bit information. The NAND flash
driver will be updated to remove the support for this different
implementation.

eMMC storage is different from a regular SD card in that it is soldered
